Each day during January, the New Suffolk eatery will post a new coupon for discounts on appetizers, meals and drinks available on its Facebook page.
Guests can redeem the coupon by printing out the offer or by showing it on their mobile device.
As a part of the celebration, Legends is teaming up with NFAWL to raise money for shelter animals on the North Fork.
You can help by sharing your “Why Legends is Legend to me” story. The restaurant will donate $2 to NFAWL for the first 300 entries, the will also double the donation if they reach 1,500 “likes” on their Facebook page.
Half of the proceeds from the sales of Legends 20th anniversary mug will also benefit NFAWL.
